SUPERHEATER-RETORT.

Specification of Letters Patent.

Patented Aug. 14, 1906.

Application filed October 28, 1903. Serial No. 178,832.

To all whom, t may concern:

Be it known that I, PHILLIP MEYER, a citi zen of the United States, residing at Santa Rosa, in the county of Sonoma and State of California, have invented certain new and useful Improvements in Retorts, of which the following is a specification.

My invention relates to improvements in retorts provided with baflies, such as are used for superheating steam or other gases, the object of my invention being to provide apparatus of the character which while conveniently manufactured shall be very effective for this purpose.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specilied, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a longitudinal vertical section of my improved retort in position in a furnace. Fig. 2 is a longitudinal horizontal section on the lines A A of Fig. 1. Figs. 3, 4, 5, and 6 are vertical cross-sections on the lines B B, O C, D D, E E of Fig. l. Figs. 7 to 12 are views similar to Figs. l to 6 of a modified form of my apparatus, Figs. 9, 10, l1, l2 being taken on the lines F F, G G, IVI H, K K of Fig. 7.

Referring to the drawings, 1 represents the retort, and 2 the wall of the furnace. In Figs. 1 to 6 said retort is made in sections which fit end to end, alternate sections having tongues 3 and grooves 4 for making a tight joint with each other. Each section has one central and two lateral vertical iiues for ermitting the passage through the retort ofp the products of combustion of the furnace. These flues, however, differ in shape, size, and location in alternate sections. In one section the central iiue 5 is of small and uniform crosssection, while in the next section the central flue 6 is of larO'er size and flares outwardly at the top. ferred to the lateral liues 7 are comparatively large and flare outward at their top, while in the second section said lateral iiues 8 are of uniform and small cross-section and do not iare at their end, although they bend outward. In consequence of this difference-in the flueepassages through the retort-sections the passages for the steam within the retort also dier. There are four such passagestwo inner and two out-er. In the irst sec- In the first section re-v tion referred to the inner passages 9 are of rectangular cross-section, their vertical sides being straight, while in the secon'd section said inner passages l0 have their sides bent outward at the top, as shown. In the first section the outer passages 11 are considerably smaller than those, l2, in the second section. By reason of this construction a highlytor tuous ath is given to the steam in its passage t rough the retort-sections and, moreover, the steam is well distributed and brought into contact with a large amount of heated surface. The construction and arrangement of the flues is also of the greatest advantage for absorption of heat from the products of combustion.

In the modification shown in Figs. 7 to l2 the shape and location of the iiues and steam-passages is identical with those in Figs. 1 to 6; but the mode of assembling the parts differs. In this case the retort itself is made in one continuous piece, and the fiues are made in separate pieces or baffles 13, which are let down into receptacles 14, formed in the retort. These pieces have shoulders 15, which rest in suitable sockets formed in the retort, and the form of the baflies corresponds to that of the iiues which they contain, as will readily be seen.

I claiml. A retort having groups of flues entirely through the retort, each group being in substantially the same transverse plane, and comprising a central and two lateral flues, the central iiue of one group being comparatively small and the lateral iiues comparatively large, and the central iiue of the neXt group being comparatively large, and the lateral flues comparatively small, and longitudinal passages in the retort between the central and lateral flues and between the lateral iiues and the wall of the retort", said passages being thus given tortuous paths, substantially as described.

2. A retort having groups of flues entirely through the retort, each group being in substantially the same transverse plane, and comprising a central and two lateral flues, the central flue of one group being comparatively small and of uniform cross-section and the lateral ues comparatively large and Haring outward at the top and the central flue of the next group being comparatively large and flaring outward at the top, and the lat- IOO eral flues comparatively small, and of unil In witness whereof I have hereunto set my form cross-section but bent outward at the hand in the presence of two subscribing Wittop, and longitudinal passages in the retort nesses.
